Cold-workable laminate

ABSTRACT

A cold-workable laminate for the production of containers for packaging of pharmaceutical and medical technical products and diagnostic agents has an aluminium film with a biaxially stretched plastic film on one side as an outer layer, and a sealing layer arranged on the second side. The aluminium film is connected with the biaxially stretched plastic film by extrusion laminating or the biaxially stretched plastic film is extrusion-coated with a polyolefin and lacquer-laminated to the aluminium film. The laminate has at least 15% higher cold-working capacity than laminates of the prior art and has improved delamination resistance.

The invention concerns a cold-workable laminate for the production of containers for packaging of pharmaceutical and medical technical products and diagnostic agents, with an aluminium film, a biaxially stretched plastic film arranged on a first side of the aluminium film as an outer layer, and a sealing layer arranged on the second side of the aluminium film.

For the production of containers for packaging of pharmaceutical and medical technical products and diagnostic agents, such as e.g. base parts of blister and push-through packs, cold-workable laminates are known with the structure of biaxially stretched plastic film/aluminium film/sealing layer (lacquer, plastic film, or plastic coating). The external plastic film is connected to the aluminium film by way of an adhesive, where the aluminium film is mainly lacquered to compensate for the influence of the coatings on the aluminium film. It has also been proposed to create the connection between an external film of biaxially stretched polyamide and the aluminium film by hot calendering, where the adhesive or laminating medium has been previously applied and dried.

With the above laminates a maximum workability by cold forming of around 30% can be achieved. The resistance to damp and heat, i.e. the resistance of the external plastic film to delamination, is maximum 26 weeks under ICH conditions.

The invention is based on the object of creating a cold-workable laminate of the type cited initially which in comparison with the laminates according to the prior art allows at least 15% more cold working and has a delamination resistance under ICH conditions of at least 52 weeks.

The object according to the invention is achieved in principle by the following two routes:

-   -   1. The aluminium film is connected with the biaxially stretched         plastic film of the outer layer by extrusion laminating.         -   The biaxially stretched plastic film of the outer layer is             preferably of the type PE (polyethylene), PP             (polypropylene), PA (polyamide), polyester, PEN             (polyethylene naphthalate), COC             (cycloolefin-ethylene-copolymer) or PS (polystyrene). The             film thickness lies in the range from 10 to 50 μm,             preferably 15 to 30 μm.         -   Suitable laminating media are adhesion-modified polyolefins,             in particular PE-MAH (polyethylene-maleic acid anhydride             graft polymer), PP-MAH (polypropylene-maleic acid anhydride             graft polymer), EVA (ethylene-vinyl acetate copolymer)-MAH             or PE copolymers, in particular EAA (ethylene acrylic acid),             EBA (ethylene-butylacrylate), EMA (ethylene-methacrylic             acid), EEA (ethylene-ethylacrylate) or ionomers. The             thickness of the extrusion lamination lies in the range of 2             to 30 μm, preferably 3 to 12 μm, as a mono-layer or             co-extruded e.g. PP-MAH/PP/PP-MAH.         -   In a particularly preferred laminate structure the outer             layer comprises a biaxially stretched (oriented) polyamide             film (oPA film) which is extrusion-laminated with PE-LLD             (linear low density)-MAH against the aluminium film.         -   The biaxially oriented plastic film and/or the aluminium             film can be coated with a primer. Suitable primers are             water- or solvent-based polyamide, PP-MAH, EAA or acrylate             or similar primers.     -   2. The biaxially stretched plastic film of the outer layer is         extrusion-coated with a polyolefin and lacquer-laminated against         the aluminium film. The side of the biaxially stretched plastic         film coated with the polyolefin can be directed against the         aluminium film or against the outside.         -   The biaxially stretched plastic film of the outer layer is             preferably of the type PE, PP, polyamide, polyester, PEN,             COC or polystyrene and is extrusion-coated with PE or PP.             The extrusion coating has an application weight in the range             of 5 to 40 g/M², preferably 10 to 30 g/M².

Both routes lead to laminates which meet the requirements with regard to degree of cold-working and delamination resistance.

The thickness of the aluminium films used for laminates according to the invention lies in the range from 20 to 100 μm, preferably 30 to 70 μm. The aluminium film can be soft or have a defined hardness.

The laminates according to the invention can be processed into packaging containers on existing packaging plants.

The inner or sealing layer can be an unstretched plastic film which is lacquer- or extrusion-laminated with the aluminium film. Preferred are plastics based on PVC (polyvinyl chloride), PVDC (polyvinylidene chloride) PE, PP, polyolefin copolymers, in particular EAA, EEA, and ionomers, polyamide, polystyrene, COC, PET, PEN or PCTFE (polychlorotetrafluoroethylene, ACLAR®). The thickness of the plastic film or combination of two or more films lies in the range from 10 to 120 μm, preferably 19 to 100 μm. The extrusion lamination can e.g. be performed with a PE terpolymer. Lacquer lamination can be performed with a watery solvent-based or solvent-free lamination media.

The sealing layer can also be a polyolefin and aluminium foil extrusion-coated with the sealing layer. Preferred sealing layers produced by extrusion coating comprise polyolefin plastics, in particular PE, PP, EAA, EAA-PE-LD or an ionomer, e.g. a sodium or zinc acrylate co- or terionomer, such as SURLYN® with an application weight in the range of 5 to 80 g/M², preferably 15 to 40 g/M², or coated with PVDC with an application weight in the range of 5 to 120 g/M², preferably 20 to 60 g/M².

Extrusion laminated sealing layers or sealing layers produced by extrusion coating are environmentally friendly as they do not require solvents and consequently do not pollute the atmosphere with VOC's.

Further preferred sealing layers are hot sealing layers based on acrylate, polybutylate, morprime, styrene acrylate with polyolefin groups, PVC/AC plus acrylate, PP/butadiene or polyester/butadiene/styrene with an application weight in the range from 2 to 20 g/m², preferably 5 to 15 g/m².

The aluminium film can also be coated with a primer and the sealing layer applied to the primer. Suitable primers are e.g. EAA or polyamide primers.

The plastic used for the sealing layer depends on the structure of the cover films provided for sealing the packaging containers made from the laminates.

Further advantages, features and details of the invention arise from the description below of preferred embodiment examples.

The table below gives a selection of cold-workable laminates constructed according to the invention with biaxially stretched, oriented polyamide (oPA) as an outer layer. The “outside” of packaging containers is the side of the laminate forming the outside, the “inside” is the side facing the plastic of a cover film as a seal, in each case with the application weight for lacquer coating or film thickness for film coating.
